Sony Xperia J approved, torn down by FCC in first 24 hours of its official existence

Of Sony's trio of Xperia phones announced yesterday at IFA 2012, we've now seen the smallest and most budget-friendly model -- the Xperia J -- make it through the mounds of red tape and federal approval. Fortunately for us, Sony didn't bother requesting confidentiality on the various teardown photos that typically are kept away from prying public eyes. As always, it's important to withhold any assumptions that this particular device will make it to any US carrier; FCC approvals never offer any guarantee, and the J's lack of LTE isn't going to help matters. Still, this seems like an ideal device for a prepaid operator to pick up, so we'll keep our fingers crossed. In the meantime, gaze upon the full teardown in the gallery below.
